Learn about the way that Monarch butterflies prepare to cross big bodies of water during their journey south for the winter, as well as ways that you can help them! Chris and Martin teach viewers that before crossing a big lake, the Monarchs sleep in the trees surrounding the lake to rest their bodies, eat nectar to fuel up, and check the wind to see if it will help them to fly south! Viewers also learn that they can help Monarch butterflies by planting butterfly gardens in their backyard, giving them a place to fuel up during their journey, as well as tagging the butterflies so that scientists can track their journey!
